A self-erecting foldable display structure has a continuous display panel supported by a collapsible frame secured to its reverse side. The support frame includes an elongated back panel and a pair of side panels integrally hinged to the respective longitudinal edges of the back panel. Transverse fold lines are formed in both the support frame and the display panel dividing the structure into a plurality of sections. A combination of flaps and elastic bands in the support frame tend to maintain the frame with a U-shaped cross-section, thereby preventing folding of the structure. Manual flattening of the side panels against the pull of the elastic bands permits the structure to be folded along the transverse fold lines into a substantially flat, compact package. When the folded structure is held at its upper end and allowed to unfold freely, the support frame automatically reassumes its U-shaped configuration and supports the display panel in a substantially vertical position.
